Working Principle
The controller continuously acquires real-time data from turbine sensors. The 50 MHz microprocessor processes this information using advanced PID algorithms to calculate the exact valve position required. It then outputs a 0-10V DC signal to the electro-hydraulic actuators, dynamically adjusting the steam or gas flow to maintain the target speed, load, or synchronization parameters while continuously executing safety protection logic.
Installation Requirements
- Must be securely mounted in a control room panel using the designated module-style mounting hardware.
- Requires a stable, clean 220V AC, 50Hz power supply with appropriate surge protection.
- Signal and communication cables must be properly shielded and routed away from high-voltage lines to prevent interference.
